We look at the division of 686743 by 70 
Let's see how many times 70 fits into 686743.

Advancing to step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 70

Going ahead to step 2:
The number 70 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 70

Advancing to step 3:
70 goes into 686 9 times with a remainder of 56.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 630 from 686, we get 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 70

Let's proceed to step 4:
When dividing 567 by 70, we get 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 560 from 567 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 70

Going ahead to step 5:
If we divide 74 by 70, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 981.0
If we subtract 70 from 74, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 70

Step 6:
70 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 9810.0
The remainder is 43 after subtracting 0 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
If we divide 430 by 70, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 9810.6
Subtract 420 from 430 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 9810.61
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 9810.614
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 9810.6142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
70 goes into 600 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9810.61428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
If we divide 400 by 70, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 9810.614285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 9810.6142857
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 9810.61428571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 9810.61428571 with a remainder of 3e-08.
